wel, his hand looks very tensed, that doesn´t mean his wrist is. I like his picking technique, mine is pretty similar, you´ll find your own anyway, if you imitate or not. You can also see Steve picking with his fingertips, what you´re also told not to do.

SUPER boring!!! Good luck trying not to all asleep through that one! The exercises are good for your technique, but most aren't very exciting musically. Better to get Gilbert's Intense Rock Complete (I and II together in one DVD).
